My CM500’s earpads are flaking pretty badly, leaving little back bits around the home office/shack. They still work fine. I purchased them in December 2012. I see that the same order has Eneloop XX batteries and a LowePro Edit 140 case, so that was all ordered to go with my brand-new KX3.
Comments on my blog post suggested the Koss SB45 as another alternative. This also has an electret mic, but somewhat different fit over the ears, and it is cheaper. https://www.amazon.com/Koss-sb45-SB-45-Communication-Stereophones/dp/B00081A2CW Do not get the Koss SB40. That is the same headset as the Yamaha CM500, but with an inferior dynamic mic. The mic connector on my Yamaha CM500 is labeled “KOSS”, for what that’s worth. I noticed that when choosing photos for my blog post. It is normal for earpads to wear out. I replaced the pads on my Grado SR225e phones after five years. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On May 6, 2020, at 8:25 AM, N2TK via Elecraft <elecraft@mailman.qth.net> > wrote: > > I bought replacement ear pad cushions and earpad covers for Koss UR20, > headphones on eBay a while back for $14.24.
